Description
The need for accurate acoustic prediction in many environments, including vehicles, aircraft, buildings, site planning, sound barriers and industrial plants, together with an increasing concern for the natural environment, has led to considerable software development and experimentation in recent years. Detailing the latest advances in this area, this book features the proceedings of the Third International Conference on Modelling and Experimental Measurements in Acoustics. Topics covered are: Ambient Noise Problems; Environmental Noise; Building Acoustics; Industrial Noise and Vibrations; Sound Absorption Barriers; Sound Reproduction and Visualisation; Aero- and Hydro-Acoustics; Underwater Acoustics; Detection Systems; Acoustic Modelling Studies; Wave Propagation; and Advanced Applications.
